IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 217,065, dated July 1,1879; application filed April 1, 1879.

\ To all whom it may concern Be it known that I, JOHN OocHRAN, J r., ofLebeck, in the county of Cedar and State of Missouri, have inventedcertain new and useful Improvements in Ohurns; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to theletters of reference markedthereon,which form a part of this specification.

My invention relates to that class of churns in which two dashers are soarranged on separate shafts as to be rotated in opposite direc tions bysuitable connection with bevel-gears; and it consists in theconstruction and combi nation of certain parts, as will be hereinafterdescribed, and set forth in the claims.

In the annexed drawings, which fully illustrate my invention, Figure 1is a central ver tical section of a churn embodying my invention. Fig. 2is a similar view, taken on the line a; as, Fig. 1; and Fig. 3 is a planview of the slide L.

A represents the'ohurn-lid, on top of which is a housing, B, forcontaining the operating mechanism. This housing is made in two parts,which are fastened to the lid an d to each other by screws, bolts, orotherconvenient means. 0 is the horizontal shaft, provided at its outerend with a crank, E, and at itsinner end with a bevel-gear wheel, D, foroperating the two sets of dashers.

G and G are the two sets of dashers. The dashers G are attached to thelower end of a sleeve, F, which passes through the lid A and into thehousing B, and within the housing said shaft is provided with abevel-gear wheel, H, which meshes with the gear-wheel D at the bottom.The dashers G are attached to the lower end of a shaft, I, which passesthrough the The bevel-gear J has bearings at b b in the housin g, whichprevent any up-and'down movement of said gear; but the shaft I has alimited up-and-down movement or adjustment by means of a wed ge-slide,L, passing through one side of the housing, and having a slot for thepassage of the shaft. The shaft has two cir cumferential collars, cl d,between which the slide L passes, and on the bottom of the lower collaris a clutch, c, to engage with a corresponding clutch on the upper endof the sleeve F.

WVhen the slide L is pushed in, the shaft 1 is raised far enough, tocause it to engage with the bevel-gear J by means of the clutch a, whilethe clutch c is disengaged, and when in this position the dashers arerotated in opposite directions. When, however, the slide L is drawnoutward, its wedge or inclined portion is retracted from under thecollar cl on shaft or rod I, and hence the said shaft drops down untilits upper clutch, a, is entirely disconnected from the gear-wheel J andits lower clutch, a, connected with a clutch, f, upon the sleeve orhollow shaft F of the lower gearwheel, H. In this position the uppergearwheel, while free to revolve, has no connection whatever with theshaft or rod I. This shaft being, however, now connected with sleeve Fby the clutch, as above stated, both dashers will be adapted to rotatetogether and in the same direction. pushed in, its inclined surface actsagainst collar d, and thereby raises shaft I until its lower clutch isfreed from the clutch on shaft F and its upper clutch brought intoengagement with a suitable groove or notches formed in the under side ofthe small upper gearwheel. In this position the two shafts F and I willbe rotated in reverse directions when the crank-handle, horizontalshaft, and gearwheels transmit motion thereto. 1

The dashers are constructed of vertical bars G and G, fastened to theends of crossbars at their upper ends, and these cross-bars arefastened, respectively, to the lower ends of the sleeve and shaft.

The vertical bars or paddles of the dashers are made T-shaped in theircross-section,which gives a flange on each side along the outer edge ofthe paddle to hold the milk to its When the wedge or slide is properplace and to prevent the cream from leaving the center of the churn.

In the lidA is a hinged door, M, and a slide, N, the former to see howthe churning is progressing, and the latter to uncover a vent for theescape of air. The lid is fastened by two hooked projections, O, and acam, P, to any suitable churn-body.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. Ina churn having two sets of dashers operated in opposite directionsby means of the bevel-gears D H J, as described, the movwedge-slide L,sleeve F, and bevel-gear J, substantially as and for the purposes hereinset forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
